Seasonal Affective Disorder or Seasonal Depression is quite common and affects at least 10 million people across the United States. In this video, the Center for Addiction and Mental Health gives a basic explanation of the signs and symptoms, common forms of treatment, and exercise as a preventative or maintenance treatment. Suggestions include light therapy, prescription medication, and/or a natural substance. Dr. Levitan also points out that Seasonal Depression can also lead to weight gain and obesity for some, though some weight gain is normal during the winter months. It is not hard to see how this can become a cycle (depression--weight gain--depression). Therefore being conscious of one's food intake as well as getting exercise can be key in helping you get control of Seasonal Depression. Seasonal Depression can be mild, moderate, or severe, and if you think it is something you might have-- visiting your doctor would be a good first step; or contacting a therapist, psychologist, or psychiatrist who can easily collaborate with your doctor if you choose. Medication may not be necessary if your depression is mild. Severe Depression should not go untreated. The good news is that this Disorder is treatable and many people find that they are able to enjoy the beauty of winter, and the many gifts it has to offer, once they get control of their depression.
